ME Association spokesman Tony Britton said: "A UK-wide ban on everybody with ME giving blood came into force on November 1.
"The blood and transplant service says this is a precaution to protect a donor's safety by ensuring that their condition is not made worse by giving blood.
"But we think it's more to do with protecting blood supplies from an unusual virus, XMRV, which in some studies has been found to be infecting the blood of people with this illness.
"We welcome the ban as a precautionary measure while the exact nature of the virus is being established."
